Answer: It sounds like you have really been trying to care for your lawn. It is important to start out by running some basic soil tests to check fertility and also soil pH. Then fertilize and/or add lime based on the test results. Next, correct mowing can really help. Set the mower at three inches and mow often enough that you do not remove more than one third the grass height at a time. (In spring you may need to mow more often than once a week.) This will encourage the grass to grow thick and shade out weeds. Finally, if the above steps do not help as much as you would like, the best time of year to try reseeding and other lawn renovation measures is in late summer to early fall. Your local Penn State county extension should be able to help you with the soil testing and interpreting the results, and in developing a lawn care program that is suited to your local soil and growing conditions. Good luck with your lawn this summer!
